Match compressed air inlets to required dewpoint
The range of desiccant compressed air dryers from Hi-Line Industries are designed to mitigate the effects of the climate change levy with low energy consumption.
Cartridge filters offer big savings
The new Filtersoft range of cartridge filters from Hi-Line Industries are claimed to offer savings of up to 50% compared to the cost of other manufacturers products
Thirteen models are available in the range, covering air flow capacities from 0.7 to 22.5m3/min at 16bar operation.
Inlet temperatures up to 60C with an ambient of 43C can be accommodated as standard, with an option for an elevated ambient of 50C also available where necessary.
A constant dew point of 2C is maintained whatever the air demand, with the dryers nevertheless operating without undue stress.
All the dryers are equipped with energy saving precooler heaters, and are supplied with five year warranties when Hi-Line pre and after filtration is also specified.
This can be extended to a full 10 years with an annual service agreement.
The latest generation of monobloc stainless-steel plate heat exchangers are used.
Their compact nature combines wide galleries with short paths which leads to highly efficient heat exchange between the compressed air and refrigerant.
The associated very wide and short air paths also ensure low air velocities with limited pressure drop.
The high material spec and non-corrosive nature of the stainless steel provides superior heat exchange qualities with none of the potential fouling associated with conventional aluminium based products.
In addition, reduced pipework with fewer couplings also helps to minimise pressure drop leading to higher savings and lower overall running costs.
Neither microprocessors nor potentially troublesome circuit boards are used in the design, eliminating the need for programming.
The products are designed for simple 'switch and go' operation and are built to ISO9001 quality standards and carry the CE mark.
